Have you considered that he's just tired--even exhausted? Or maybe not well? You said he's a shift worker. He may not be getting enough sleep. Try keeping his schedule and see what it does to you. The cause of all this may be something you're not yet aware of. Don't start with a prescription until you've really diagnosed the cause. As hard as it sounds, ask him what's up--talk to him, tell him your frustrations. What do you have to lose? And have him read this forum. This is my first time here. What a terrific resource! And it's not porn!!
